Vin s. 1 .gIt-is therefore the objectof my mventlon vt provide means whereby the drum and bearin may be assembled in a single unit and adjusted'on'abench, and later applied te the shaft on which the idrum is designed to operate,and having means .whereby thesaid bearing and drum may be easil and qulckly attached or'detached and rigi ly` secured in position, thus providing means whereby the operator may easily and quickl remove the drum and its bearing from the s aft and take it to the nearest automobile garage where ,the bearings may be adjusted by men fa- 95 miliar with this type of bearing. l

My invention consists in the construction,

arrangement and combination of the various parts off thev device, whereby the ob] ects contemplated arev attained, as hereinafter more 30 fully set'forth, pointed vout in my claims,

and lillustrated in the accompanying drawin which:

'lfigure lis a longitudinal sectional'view of the drum and the bea-ring for supporting the same, showing the manner in which they Y are' applied to the xed shaft.

F'gure 2 is a sectional viewtaken onlthe line 2-2 of Fi re 1. -The. n u'mera 10 indicates a su port in 4, which is mounted afixed. shaft 11. yujlilported on the shaft `11isa sleeve'12, eac end of whichis provided with a contracted portion 1'3; Each of the contracted ortions 13 is designed to' carry a conical rol er bearing14 of theordinary t e. contracted portions has a xed race 15 mounted on the sleeve '12. Rotary races 16 are mounted-in the hub 17 v.ofthe-cable drum 18. The races 16 are adjustably mounted in said hubby-means of annular adjusting plates l19, said plates being threaded of. the hub 17 and locked in-an adjusted po.

Each of the sition by means of set screws 20.

The inner edge of the annularmembers 19 are rovided with an annular groove 21- in whic is mounted a packing 22.

- The sleeve 12 is adapted to be slid on to into the ends ,and oli .of the end of the shaft 11 and to` carry with `it the bearings. 14, the hub 17 and the drum 18, thus providing a complete bearing when assembled, in which the proper adjustmentof the rollers 14' may be made (sol through the -annular members 19. Said ad- I justment is 4made by placing the sleeve 1 2v on a temporary mandrel or shaft, after which the sleeve 12 may be placed on the shaft 11.

The said sleeve 12 may then be secured against longitudinal movement by means of' collars23,v each of which has its inner edge provided with an annular groove'or recess 24 for; receiving the outer ends of the portions `13. The inner ends of the collars 2 3 are designed to abut the outer ends of the xed -races 15. Said collars 23 are lixed to the shaft by suitable set screws 25, which extend through grooves 26 in the end svof the members 13, and thusprovide means for anchoring the sleeve against anyl slight rotary movement relative to the s aft, which might be caused by the friction ofthe rollrotated.

Said packing makes contact with the periphery of said collars to'form an o il tight joint between thev collar andv the members 19.- This space 27 between the sleeve 12 and the hub 17 maybe i1led,or partially filled, with oil or grease.l

be built in various units, which may be adjusted and assembled Within themselves and placed in stock, so that the completed machine may be easily and quickly assembled when so desired; v

I claim as my invention:

l. In a device drum hub having an opening, a sleeve supeach end of said sleeve being provided With a contracted cylindrical portion, roller bearings for rotatively mounting said hub on said sleeve, `the inner races of said bearings being supported by the contracted portions of said sleeve, the outer races of said bearings being mounted in said hub, means for adjusting said outer races Within said hub and with respect to the rollers of said bearings and said inner races, and means for fixing the inner races of said bearings against outward movement longitudinally of said sleeve, and said sleeve against longitudinal and rotary movement when mounted on a shaft, said means comprising a collar supported at each end of said sleeve,

the inner endsof the inner faces of said collars being designed to engage the outer faces of the inner races of said bearings and provided With an annular recess to overlap the ends of the contracted portions of said sleeve, and setscrevvs projecting through the overlapping portion of said collars and through the contracted portions of said with the shaft on which the sleeve is mounted.

2. In a device of the class described, a drum hub` having an opening, a sleeve supported therein, each end of said sleeve being provided With a contracted cylindrical portion, a roller bearing for each end of said sleeve, the inner races of said bearings be- `ing mounted on said contracted portions,

means for fixing the inner races of said bearings against outward movement longitudinally of said sleeve and said sleeve against longitudinal and rotary movement When mounted on said shaft, said means comprising a collar supported at eachend ofvsaid sleeve, the inner ends ofthe inner faces of said collars being designed to engage the outer faces of the inner races of 'said bearings and provided with an annular recess `to overlap the ends of the contracted portions of said sleeve, set screws project,- ing through the overlapping portions of said collars and through the of said sleeves, and into engagement With the shaft on which the sleeve is mounted.v GEORGE T.
